Nicholas O'Donnell was very high in Nemesis' eyes. Being one of her favourite children she watched him carefully. When he committed suicide Nemesis didn't have the heart to bring him back. Instead, she took his sense of good and evil - her favourite feature of his - and kept them hidden away. A year from his death, she took the two senses and turned them to two babies inside of her. For a few months she remained pregnant but hearing that Hades was going to target the two, she went and impregnated two women, Hwang Hea-Jung and Xi Yesha with the two children, allowing their DNA to mix in with the babies in an attempt to save them. Both women had suffered many miscarriages and stillbirths and when they awoke to find themselves pregnant, they were overjoyed. Nemesis kept an eye on the two women as they carried her children. Within 9 months the two women gave birth on the 10th May 1996.
Xi Yesha is a woman who's well manipulated by her parents resulting for her loneliness, she despises both her parents and her "husband" as they were all the same; control freak, however the mortal was raised to obey orders and disobeying them will come with great consequences. Yesha has been hoping for a child of her own-- to have someone she can pour her love but it caused her great frustration to know that she's not well capable of having a baby. Then a goddess occured in one of her dreams, Yesha was entrusted to give birth to the goddess' child and the full responsibilities that a demigod need from it's guardian, everything was surreal for the mortal however to be clear and sure, the young lady took pregnancy tests and all confirmed her carriage for the baby. Her parents were thrilled to know that someone would take over on their company but Yesha was the only one to know that her child is a demigod.
Yesha gave birth to Lei, Nemesis came into her dreams and told her that her child had a twin name "Hwang Tae-Hyun". Yesha vowed to protect Lei with all her might, when Lei turned 3, she took him to America leaving her husband to work on for her parent's company, the young lady promised to be back after Lei had finished his education. That way she was able to do everything that is necessary .
At the age of 10, Lei was taught basic skills on how to defend himself when in danger by Yesha he was also given a wristwatch by Yesha that came from Nemesis she told him that it would only protect him. Nemesis appeared in her dreams to warn her that when Lei was 11, danger would come. Yesha, on the other, had an affair with another guy.
After a while, Lei's mortal father gave them a surprised visit however he was surprised and knew about Yesha's affair, ofcourse the mortal was enraged that he killed the poor young Yesha-- since it was all a mistake he took Lei back to China and told his in laws that their house in states were robbed and he found Lei hiding while Yesha was found lying on the floor after all the lies he threatened to kill Lei if ever Lei tries to spill the truth. Nemesis was angered that she cursed Xi family to have experience on being poor like beggars on the street. and brought justice for Yesha, she pulled out the good fortunes from the family resulting for bankruptcy of their company
Coming at the age of 12, the in laws sought for the help of their partners since Lei isn't any of the help, he was sent back to America to continue his education unfortunately without Yesha-- who knew Lei's identity it leaves Lei bare on any monster that would come therefore the goddess herself sent a Satyr as a fellow mate in Lei's class. At the same year their campus held an astronomy camp using the nearby woods and ofcourse at night. There were tents provided by the school admins and each can give shelter to two students so Lei and his Satyr friend-- Kiel paired together at that night the two wandered off to the camp fire as they were both confident that they'll be able to go back as the fire's smoke was escaping through the woods however, since it's the woods an harpy caught the demigod's scent. The harpy was agressive for it was hungry and the sight and smell of Lei made it come dashing towards him without thinking twice. Being panicked the young man ran for his life but his friend was nowhere to be found, while running for his life and finding his best friend the son of Nemesis tripped with his wristwatch hitting the ground it evolved into a shield. Before the harpy could rip the hell out of him he turned and used the shield causing the harpy to hit her head on the shield then his friend came back with a sword with him and threw it at Lei's direction, as soon as the Harpy got over of her daze she once dashed over to Lei but was surprised to see her torso pierced with the sword with the demigod looking at him, terrified. Without a moment the monster disintegrated and it seemed as if nothing happened but Lei was left with few scrapes.
At the age of 13 Nemesis was still aware that Hades was hunting down for the twins so Nemesis demanded the Satyr she sent to take Lei in camp as soon as he can. Unfortunately Lei was picked up by his father in America to bring him back to China. The plane crashed on Yellow Sea near Korea and Lei woke up in the shore one of Jeju's beaches. He was woken by the tourist who saw and asked for help which was Han-soo.
A former CEO of an Entertainment, Jang Han-Soo, took responsibility over him and gave him a new name; Song Joo-won. What was left of him was only the watch. He had his second monster attack when Hades knew that he was one of the twins that Nemesis hid, so he sent a Fury kill him. Lei/Joo-won was wandering on a private beach which happened to have a forest nearby, in the middle of the night, struggling if he could remember some piece of his life before the plane crashed when he soon heard a weird noises which was a fury getting ready to kill Joo-won.
Out of the blue he noticed a button on the wrist watch below in the center,. He came back to his senses, seeing the Fury flying over him, he used his wrist on not to fall on his back which was quite hard, he noticed his watch suddenly turning into a sword. Seeing the Fury getting ready for it's attack, he grabbed the sword and stabbed the monster's chest, killing it.
At 14, a rumour spread that his guardian Han-Soo had a son and Joo-won was interviewed by many and it was also said that Han-Soo wanted him to try being an idol or an actor as a career. Few months later when his career was becoming a success he was attacked by a Cyclops on his hiking with his Kyung-Soo and another friend who was a former Huntress. They were all safe and sound after the Cyclops' attack had been stopped by the former huntress. After that the huntress took Joo-won to Camp.
4 years later, at 18, he had gone back to South Korea to continue on his career. When he came back he found out that his guardian Kyung-Soo had died whilst he was at the camp. He continued his career for only a few months before deciding to go back to Camp at the nearest time possible. Near the entrance of the camp Parkjoo was not aware that a flock of Stymphilian birds had caught his scent. They came rushing down to Parkjoo pointing their sharp beaks at him. Attaining few streaks of wound he forced himself to ran inside the camp. After all that he was quickly claimed by Nemesis
